These are simply linked to the CPU through a connector. If additional inputs/outputs are required, a variety of different expansion modules is available. With PG/PC or OP as master, a maximum of 31 SIMATIC S7-200 devices can be connected together. The SIMATIC S7-300 universal Controllers saves on installation space and features a modular design.

The PPI interface built into all CPUs enables point-to-point connections to PG/PC, SIMATIC OP, expanded SIMATIC S7-200 and user-defined end devices (printer, bar code reader). The legendary universal PLC The SIMATIC S7-300 is used in many applications worldwide and has been proven successful millions of times. The CPUs are each offered in 5 different variants, with various connection and control voltages. Laboratory: Laboratory mixers, heating cabinets, vacuum pumps, suction equipment. įood industry: Kneading, cutting machines, mixing granulators.Small and special machine construction: Packaging, encompassing and winding machines The products of the S7-200 family which are optimally matched to each other also make it easy to change and expand the automation solution in the future.

The newly available CPU types and expansion modules allow universal automation concepts with 10 to 248 inputs/outputs. If one of the time stamps is not current, then this could indicate an issue with that device or the connection of that device.The Siemens SIMATIC S7-200 family offers a broad range of modules appropriate for the most wide-ranging applications.

Save the hardware configuration which only saves into the local windows PC project files.Īs a diagnostic check, a successful connection will show a current time stamp status on all devices as shown below on the web page “Manage My Remote” on the website. Original settings are shown restored below. Now we are done with our monitoring, so we go back to the Hardware configuration screen and open the Ethernet module to reset its properties back to their original state.Ĭhange these IP addresses back to the original settings. The status below shows connected to the PLC. Then we click on the eye glasses which puts this VAT online with the PLC and also puts the VAT table into live monitoring mode. Next we go back to the main Simatic Manager and open Test VAT In our test we are just going online with the PLC to observe a VAT table. Then save the configuration (remember this just saves it in the windows PC project only, be careful not to do any hardware configuration updates on this PLC ethernet module. We also, checked do not use router as it is not required since our tech support gateway is on the same subnet as our development PC that is running the Step 7 development software. We changed the IP address to match that of our technical support gateway, and the subnet mask must be the same as the technical support gateway subnet. This started as a port of knollearys MQTT library for Arduino & ESP8266. Record the IP address and Router address if it is used before making changes. MQTT-Siemens-S7-300 MQTT library block written in SCL for S7-300 with internal (PN) or external (CP) Ethernet. Click on the properties box as shown below: The range of applications of the SIMATIC S7-300 is widespread, especially in all kinds of machine. It was introduced as the successor to the Simatic S5 in 1995. Upon publication of a product phase-out announcement, the respective product will be available as a spare part for a period of ten more years. The Simatic S7-300 is a controller for the lower to medium performance level of the company Siemens. We are going to temporarily change the IP address in the project only, and then restore it later after we finish this session. The SIMATIC S7-300/ET 200M system families are part of our established product range and will definitely be available until 2023. This opens the Properties box for this ethernet module. Then double click on the etherne module as shown below: Next open the Siemens project and find the Hardware configuration line as shown and by double clicking open the Hardware configuration screen. We entered the Field Device TCP Port number 102 which was found by clicking on, “ Click for a list of common TCP Ports” shown on the “Manage My Remote” screen, and we entered the hardware configured IP address of the PLC as 10.0.5.15 in the Field Device IP Address box. First login to your web page “Manage My Remote” on the website. The PLC resided on a private 10.0.5.x subnet using a CP 343-1 ethernet module. This is a remote connection session to a Siemens S7-300 PLC on Ethernet using Siemens Step 7 Simatic Software.
